A GPS Navigation Code System comprising either a smart cell phone or a personal data assistant (PDA) having GPS features and easy address retrieval means, thereby enabling a driver to retrieve and request directions to an address. The user pre-programs the system with a plurality of addressees or points of interest and assigns unique navigation codes for each. While driving, the user presses a special address search mode key and inputs the unique navigation code by keyboard or speech pattern, views displayed address and accepts the same. When an unknown navigation code is entered, the GPS accesses a remote database through the Internet to recover the associated company name and business GPS coordinates. The remote database computes travel distance based on vehicle and business GPS coordinates, creating an ordered list that is presented to the GPS user, together with directions by map and speech on a turn-by-turn basis. |

1. A GPS Navigation Code System comprising:
a. a smart cell phone having Internet connectivity, a local database, an internal map database, display monitor, memory, processor, software generated or hardware data entry keyboard, sound input, sound output and a special key for activating address search; b. said smart cell phone being programmed by a user through a software generated or hardware data entry keyboard to record various addresses and points of interest; c. said user assigning a contracted navigation code reference to each of the addresses and points of interest; d. said user recording a speech pattern of sounds for each of the navigational codes for each of the addresses and points of interest; e. said smart cell phone storing in a local database information collected and linking said addresses, points of interest, contracted navigational code reference and speech pattern of sounds in three linked separate databases; f. said special key being operative, upon being pressed, to thereby set the device in address search mode, whereupon a desired address is retrieved from the stored database and displayed on the monitor when the user types a few characters on the software generated or data entry keyboard or speaks the previously assigned speech pattern of sounds; g. said user accepting the displayed address by pressing a special key and canceling the address search mode of said smart cell phone; h. said GPS navigation system calculating the route to the desired address selected and displaying the route on the display as well as providing voice generated guidance using said internal map database; i. said GPS navigation system being operative in response to communication of a contracted navigation code that is not present in the local database therewithin to access the Internet and connect to a remote database containing advertised contracted navigation codes and names of specific businesses and the GPS longitude and latitude of the business entered and managed by the owner/administrator of the remote database; j. the GPS navigation system being further operative to access said remote database providing current GPS longitude and latitude coordinates of the GPS unit in the vehicle; k. the remote database computer searching through the entire database matching contracted navigation code and computing driving distances based on business GPS coordinates and vehicle GPS coordinates, and creating an ordered list according to driving distances, all entries having driving distance less than a specified driving distance range; l. the user selecting a particular business location from the list presented and the GPS coordinates of said selected business transferred to the GPS mapping software; whereby the user after pressing the special key on the GPS navigator device spends a shorter time, entering a few navigational code characters or speaking the previously assigned speech pattern, when retrieving the destination address, thereby avoiding distractions from vehicular driving duties, increasing the margin of safety for the driver, passengers and others in the vicinity of the vehicle. |
